DETAILED DESCRIPTION

Various apparatuses or methods will be described below to provide an example of an embodiment of each claimed invention. No embodiment described below limits any claimed invention and any claimed invention may cover apparatuses and methods that differ from those described below. The claimed inventions are not limited to apparatuses and methods having all of the features of any one apparatus or method described below, or to features common to multiple or all of the apparatuses or methods described below. It is possible that an apparatus or method described below is not an embodiment of any claimed invention. Any invention disclosed in an apparatus or method described below that is not claimed in this document may be the subject matter of another protective instrument, for example, a continuing patent application, and the applicant(s), inventor(s) and/or owner(s) do not intend to abandon, disclaim or dedicate to the public any such invention by its disclosure in this document.

Referring to FIG. 1, an example of a peat moss processing apparatus is shown generally at reference numeral 10. In the example illustrated, the apparatus 10 includes a top portion 12, a middle portion 14, a transition portion 16 and a bottom portion 18.

The peat moss to be processed may be fed to the apparatus 10 through the top portion 12. In the example illustrated, the top portion 12 includes an inlet or first opening 20. The first opening 20 may receive the peat moss to be processed. For example, a tractor equipped with a screening bucket or other suitable loading device may deposit peat moss into the first opening 20. In the example illustrated, the bottom portion 18 includes an outlet or second opening 22. Processed peat moss may be discharged from the apparatus 10 through the second opening 22.

In the example illustrated, the apparatus 10 is upright, with its height being substantially greater than its width or depth. The apparatus 10 may have a height, for example and not intended to be limiting, between 4 to 20 feet. The apparatus 10 may be made of stainless steel, or coated carbon steel, mild steel or other suitable material. As illustrated, the apparatus 10 may have a generally rectangular cross section to minimize its footprint for a given interior volume, and to provide structural integrity and ease of manufacture. However, in other examples, the apparatus may have a generally circular or polygonal cross section.

In the example illustrated, the apparatus 10 is generally deeper at the top portion 12 and narrower at the bottom portion 18. As shown in FIG. 1, the top portion has declined front and rear sides 24 to provide for a decrease in interior cross section as materials move downwardly from the first opening 20 to the middle portion 14. The apparatus 10 also tapers at the transition portion 16, with declined front and rear sides 26 that provide for a decrease in interior cross section as materials move downwardly through the transition portion 16 to the bottom portion 18. The middle portion 14 and the bottom portion 18 are each shown to be generally cuboidal in shape.

In the example illustrated, a flow regulator 28 is located at the bottom of the top portion 12. The top portion 12 with the flow regulator 28 may act as a hopper to regulate the flow of peat moss entering the apparatus 10. As shown in FIG. 1, the flow regulator 28 may include a plurality of bars 30 and gaps 32 arranged between the bars 30.

In some examples, the flow regulator may be operated between a closed state in which peat moss is prevented from entering the apparatus and an open state in which peat moss is allowed to enter the apparatus. In such examples, a sliding gate (not shown) may be implemented and controlled to vary the size of the gaps and thus adjusted to vary the amount of peat moss accepted into the apparatus.

Referring to FIG. 2, the flow regulator 28 is shown positioned at the bottom of the top portion 12. The apparatus 10 further includes a feed roller 34. In the example illustrated, the feed roller 34 is located immediately below the flow regulator 28, and together the flow regulator 28 and the feed roller 34 may be referred to as a feeding mechanism for the apparatus 10. In operation, the feed roller 34 rotates about its axis to deliver materials from the top portion 12 to the middle portion 14. The speed of rotation of the feed roller 34 may be adjustable and varied to control the rate at which peat moss is passed to the middle portion 14. In some examples, a control system (not shown) may be configured to control the rotational speed of the feed roller 34. The control system may also be configured to control the flow regulator in examples where the flow regulator is operable between closed and opened states.

The feed roller 34 is shown to include a plurality of teeth 36 that are disposed about the periphery of the feed roller 34 and extend outwardly therefrom. Referring to FIG. 3, the teeth 36 are shown to extend at least partially through the gaps 32 between the bars 30 of the flow regulator 28. This arrangement may help to facilitate breaking up and/or mixing of the peat moss material, and may assist in delivering the peat moss through the gaps 32 to the middle portion 14 of the apparatus 10.

Referring to FIG. 4, the teeth 36 are shown arranged in rings which have an angular offset between them extending across the cylindrical outer surface of the feed roller 34. However, the pattern of teeth may vary and may take the form of another suitable grid layout.

After passing through the feeding mechanism, the peat moss may then pass through a guiding mechanism. In some examples, the guiding mechanism includes one or more sloping guide plates which may be perforated to allow liquid to pass through while still supporting the peat moss so that at least some of the moisture in the peat moss may be drained away. In some examples, the guides may form an angle of that is between 10 and 45 degrees with the interior wall of the apparatus. In some examples, the guides may form an angle of about 15 degrees with the interior wall of the apparatus. In some examples, one or more of the guide plates may also be vibrated to further facilitate dewatering of the peat moss.

Referring to again to FIG. 2, the apparatus 10 is shown to include guide plates 38, 40. In the example illustrated, the guide plates 38, 40 are located under the feed roller 34, and peat moss may fall from the feed roller 34 to the guide plates 38, 40 under the force of gravity. The guide plates 38, 40 are arranged to form an angle with interior side surfaces of the apparatus 10, which may be varied. Although not shown, in some examples, the guide plates of the guiding mechanism may include perforations and/or a vibration mechanism to enhance the dewatering of the peat moss.

In the example illustrated, the guide plates 38, 40 serve to direct the peat moss from the feed roller 34 to a compression mechanism. In FIG. 2, the compression mechanism is shown to include a first roller assembly having an upper roller 42 and a lower roller 44. The rollers 42, 44 are arranged in the middle portion 14 of the apparatus 10. The guide plate 38 serves to direct the peat moss to the upper roller 42, and the guide plate 40 is arranged to direct the peat moss between the rollers 42, 44.

The rollers 42, 44 are positioned and configured to press the peat moss for dewatering. The speed of rotation of the rollers 42, 44 and/or the distance between the rollers 42, 44 may be controlled and adjustable to vary the extraction of moisture from the peat moss.

In some examples, the upper roller 42 may be made of a solid material and have a relatively smooth exterior cylindrical surface. In other examples, the upper roller 42 may have a corrugated or otherwise textured outer surface, which may assist in providing traction to move the peat moss.

In some examples, the lower roller 44 may include a plurality of perforations distributed over its exterior cylindrical surface. Referring to FIG. 5, the lower roller 44 is shown to have an outer surface 60 and perforations 62 are disposed uniformly across the outer surface 60. When peat moss is forced to pass between the rollers 42, 44, liquid may be forced through the perforations to effect dewatering of the peat moss. The perforations 62 may be sized to allow water to flow through but are small enough to prevent peat moss particles from passing through. Coupled to and/or included within the lower roller 44, a conduit (not shown) may be used to direct liquid collected through the perforations 62 to a reservoir (not shown) for removal from the apparatus 10.

As illustrated, the compression mechanism may further include a second roller assembly having an upper roller 46 and a lower roller 48. The rollers 46, 48 are arranged in the bottom portion 18 of the apparatus 10. The guide plate 50 is arranged to direct the peat moss between the rollers 46, 48. The rollers 46, 48 are also configured to press the peat moss for dewatering, and the speed of rotation and/or the distance between them may be controlled and adjustable.

In some examples, there may be no gap between the upper and lower rollers, i.e. they may be pressed together, and the upper roller may be biased towards the lower roller (e.g., spring loaded, or alternatively using an air bag system) to maintain pressure between the two rollers. In such examples, as the peat moss is forced between the rollers, the upper roller will move up, while still keeping a generally constant pressure on the peat moss passing between the two rollers.

The upper roller 46 may be have a relatively smooth outer surface or textured outer surface. The lower roller 48 may also include perforations, and a conduit (not shown) may be used to direct the liquid collected by the lower roller 48 to a reservoir (not shown). After passing through the rollers 46, 48, the processed peat moss may exit the apparatus 10 through the second opening 22.

The first and second roller assemblies may be adjustable and used in different ways to separate water from the peat moss. Depending on the moisture content of the peat moss being processed by the apparatus 10, and the desired moisture content after processing, it may be useful to configure the first roller assembly to remove approximately 20 to 50% of the moisture content from the peat moss, and configure the second roller assembly to remove approximately 60 to 90% of the moisture content from the peat moss.

In the example illustrated, the compression mechanism includes two roller assemblies. However, it will be appreciated that, in other examples, the compression mechanism may consist of a single roller assembly, or three or more roller assemblies. Also, each of the roller assemblies in the example illustrated consists of two rollers. It will be appreciated that other roller assembly configurations may be possible, in which there is a single roller and another stationary element, or other roller assemblies having three or more rollers therein. Various configurations are possible.

The apparatus may further include one or more fluid injection mechanisms (not shown). For example, a mechanism may be used to direct compressed air towards a top surface of the guide plates to urge the peat moss towards the roller assembly of the compression mechanism. A mechanism may also be used to blow compressed air through perforations of the guide plates, to clean them in the event that peat moss is clogging the perforations. Similarly, a fluid (such as compressed air or water) may be injected into the perforations of the lower roller to remove any debris that is blocking the perforations. This mechanism may be used to push the fluid from the inside of the lower roller outwardly. A fluid injection mechanism may also be configured to inject a fluid (such as water, air, or any other suitable fluid) into the peat moss that is entering the apparatus, or within the apparatus. This may be done, for example, using compressed air, to control movement of the peat moss through the feed mechanism. Alternatively or additionally, water may be injected to ensure that the peat moss entering or within the apparatus is uniformly moist, prior to dewatering by the compression mechanism.

Referring now to FIG. 6, an example of a peat moss processing system is shown generally at reference numeral 52. The system 52 includes a plurality of the apparatuses 10 arranged in parallel. In the example illustrated, a tractor 54 has a screening bucket 56 that may scoop peat moss at a field location and then deliver the peat moss to the inlets of the apparatuses 10. Once the peat moss has been processed by the apparatuses 10, the peat moss may be received onto a conveyor mechanism 58. The conveyor mechanism 58 is shown positioned underneath the outlet of each of the apparatuses 10 and receives the processed peat moss that exits the outlet. The conveyor mechanism 58 may direct the peat moss for further processing. For example, the peat moss may be conveyed to an onsite drying unit, or into a trailer for offsite drying. Once the product reaches the desired humidity level, it may be bagged and shipped.

Referring to FIGS. 7, 8A, 8B, 9 and 12, another example of a peat moss processing apparatus is shown generally at reference numeral 70. The apparatus 70 may be made of stainless steel, or coated carbon steel, mild steel or other suitable material. The apparatus 70 includes a top portion 68 and a middle portion 69. Peat moss to be processed may be fed to the apparatus 70 through the top portion 68. In FIG. 7, the top portion 68 is shown to include an opening 71 for receiving the peat moss to be processed. For example, a tractor equipped with a screening bucket or other suitable loading device may deposit peat moss into the opening 71 of the top portion 68.

As shown in FIG. 7, the top portion 68 has declined front and rear sides 72 to provide for a decrease in interior cross section as materials move downwardly from the opening 71 to the middle portion 69.

Flow regulators may be located at the bottom portion of the top portion. In the example illustrated, feed rollers 73 are shown located in the middle portion 69 and extend upwards to the top portion 68. The feed rollers 73 may regulate the flow of peat moss moving from the top portion 68 and entering the middle portion 69 of the apparatus 70. The speed of rotation of the feed rollers 73 may be adjustable to vary the rate at which peat moss is directed to enter the middle portion 69. In some examples, a control system (not shown) may be used to control operation of the feed rollers 73.

In the example illustrated, the middle portion 69 of the apparatus 70 is divided into four separate chambers 75, each being under the top portion 68. In the example illustrated, each of the chambers 75 is upright, with its height being substantially greater than its width or depth. Each of the chambers 75 of the middle portion 69 may have a height, for example and not intended to be limiting, between 4 to 20 feet. As illustrated, each of the chambers 75 may have a generally rectangular cross section to minimize its footprint for a given interior volume, and to provide structural integrity and ease of manufacture. However, in other examples, the apparatus may have a generally circular or polygonal cross section.

Referring to FIG. 8A, each of the chambers 75 has a top opening 80. The top opening 80 for each of the chambers 75 may be configured to vary in depth and width dimensions depending on peat moss processing needs. In the example illustrated, an adjustable structure 77 is shown attached to a top portion of an internal wall 78 of each of the chambers 75. The adjustable structure 77 and the feed roller 73 may cooperate to define a gap 82 for allowing peat moss to enter the chamber 75. In some examples, the width and/or depth of the structure 77 may be adjustable. In some examples, the structure 77 may be removable, i.e. detachable from the internal wall 78.

Referring to FIG. 8B, a gap 76 is shown between an outer periphery of the feed roller 73 and the adjustable structure 77, which determines how much peat moss may enter each of the chambers 75. In some examples, the adjustable structure 77 may be used to block the opening 80 of the chamber 75. When there are multiple chambers 75 in parallel, the adjustable structures 77 may be selectively used to prevent peat moss from entering some of the chambers 75. This may allow selection of chambers for peat moss processing in case of one or more chambers become defective and needs maintenance.

The feed rollers 73 are shown to include a plurality of teeth. Referring to FIGS. 10A and 10B, teeth 101 are shown disposed about the external surface of the feed roller 73. Each of the teeth 101 extend radially outwardly and along a longitudinal extent of the feed roller 73. In the example illustrated, there are sixth of the teeth 101 which take the form of a cylindrical star shape. The teeth 101 may be formed of one or more sheets of material that are fastened to the feed roller 73 through apertures 103. Referring to FIG. 10B, each of the teeth 101 may include a hook feature 107 that is disposed at an outer tip.

Referring to FIGS. 8B, 9, 12 and 13, the apparatus 70 is shown to include guide plates 83, 84. In the example illustrated, the guide plates 83, 84 in each of the chambers 75 are located under the feed roller 73, and peat moss may fall from the feed roller 73 to the guide plates 83, 84 under the force of gravity. The guide plates 83, 84 are arranged to form an angle with interior side surfaces of the apparatus 70, which may be varied. Although not shown, in some examples, the guide plates of the guiding mechanism may include perforations and/or a vibration mechanism to enhance the dewatering of the peat moss.

In the example illustrated, the guide plates 83, 84 serve to direct the peat moss from the feed roller 73 to a compression mechanism. The compression mechanism is shown to include a roller assembly having an upper roller 87 and a lower roller 88. The rollers 87, 88 are arranged in the middle portion 69 of the apparatus 70. The guide plate 83 serves to direct the peat moss to the upper roller 87, and the guide plate 84 is arranged to direct the peat moss to the lower roller 88.

The rollers 87, 88 are positioned and configured to press the peat moss for dewatering. The speed of rotation of the rollers 87, 88 and/or the distance between the rollers 87, 88 may be controlled and adjustable to vary the extraction of moisture from the peat moss.

In some examples, the upper roller 87 may be made of a solid material and have a relatively smooth exterior cylindrical surface. In other examples, the upper roller 87 may have a corrugated or otherwise textured outer surface, which may assist in providing traction to move the peat moss.

In some examples, the lower roller 88 may include a plurality of perforations distributed over its exterior cylindrical surface. Referring to FIG. 11, the lower roller 88 is shown to have an outer surface 111 and perforations 113 are disposed uniformly across the outer surface 111. When peat moss is forced to pass between the rollers 87, 88, peat moss liquid may be forced through the perforations to effect dewatering of the peat moss. The perforations 113 may be sized to allow water to flow through but may be small enough to prevent peat moss particles from passing through.

In some examples, there may be no gap between the upper and lower rollers, i.e. they may be pressed together, and the upper roller may be biased towards the lower roller (e.g., spring loaded, or alternatively using an air bag system) to maintain pressure between the two rollers. In such examples, as the peat moss is forced between the rollers, the upper roller will move up, while still keeping a generally constant pressure on the peat moss passing between the two rollers.

In the example illustrated, there is shown a reservoir 89 under the lower roller 88 for collecting liquid from the perforations of the lower roller 88. In the example illustrated, the reservoir 89 has a V shape, and may include an outlet for draining liquid from the apparatus 70. Coupled to and/or included within the lower roller 88, a conduit (not shown) may be used to direct liquid collected through the perforations 62 to the reservoir 89 for removal from the apparatus 70.

Referring to FIG. 8B, additional guide plates 85, 86 are positioned under the rollers 87, 88 for directing compressed peat moss to the bottom of the apparatus 70, which may be open and a conveyor mechanism may be located under the apparatus.

Referring now to FIG. 12, an example of a peat moss processing system is shown. In the example illustrated, the system includes the apparatus 70 and a screening bucket 122 that may scoop peat moss at a field location and then deliver the peat moss to the apparatus 70. Once the peat moss has been processed by the apparatus 70, the peat moss may be received onto a conveyor mechanism 130. The conveyor mechanism 130 is shown positioned underneath the apparatus 70. The conveyor mechanism may direct the peat moss for further processing. For example, the peat moss may be conveyed to an onsite drying unit, or into a trailer for offsite drying. Once the product reaches the desired humidity level, it may be bagged and shipped.
